The probe assembly 5 includes a female pin base 507 fixed inside the probe housing 3, a limit pin 508 is fixedly installed on the female pin base 507, and disassembly mechanisms 6 are provided at both ends of the male pin base 505. Through the cooperation of the male pin base 505 and the female pin base 507, the array elements 502 on the circuit board 501 can be quickly installed. At the same time, the disassembly mechanisms 6 can remove the circuit board 501 and the array elements 502 together when the probe front housing 4 is removed, improving the disassembly speed and facilitating user maintenance.

[0025] Please refer to again Figure 2 and Figure 3 , The probe assembly 5 includes a female pin base 507 fixed inside the probe housing 3, a circuit board 501 is connected to the female pin base 507, array elements 502 are fixedly installed at the bottom of the circuit board 501, a male pin base 505 is fixedly installed on the upper surface of the circuit board 501, a limit card slot 504 is opened on the male pin base 505, a limit pin 508 is fixedly installed on the female pin base 507, the probe assembly 5 further includes a connecting pin 506 fixed on the male pin base 505, and a movable notch 503 is opened on the circuit board 501.

[0026] Specifically, the driving frame 601 can drive the second convex block 605 to move upward. When the second convex block 605 moves upward, it will drive the circuit board 501 to move upward. When the circuit board 501 moves upward, it will drive the connecting pin 506 on the male pin base 505 to move upward, so that the connecting pin 506 is inserted into the female pin base 507, and the limit pin 508 is embedded in the limit card slot 504, fixing the male pin base 505 and the female pin base 507 together and quickly installing the array elements 502 on the circuit board 501.

[0027] Please refer to again Figure 2 and Figure 4 , The disassembly mechanism 6 includes a positioning sleeve 604 fixed on the male pin base 505, a driving frame 601 is fixedly installed on the probe front housing 4, a positioning sleeve 603 is fixedly installed on the positioning sleeve 604, a return spring 606 is provided inside the positioning sleeve 603, a push rod 607 is movably installed on the positioning sleeve 603, and the disassembly mechanism 6 further includes a first convex block 602 fixed at the upper end of the driving frame 601, and a second convex block 605 is fixedly installed below the first convex block 602.

[0028] Specifically, the driving frame 601 can drive the first convex block 602 to move downward. When the driving frame 601 moves downward to the bottom dead center, the through hole on the positioning sleeve 604 will be aligned with the through hole on the driving frame 601. After the through hole on the positioning sleeve 604 is aligned with the through hole on the driving frame 601, the return spring 606 will push the ejector rod 607 forward. The ejector rod 607 is used to push the limit pin 504 out of the limit slot 508, making the pin male seat 505 loose from the pin female seat 507. When the first convex block 602 moves downward, it will press down the pin male seat 505, and when removing the probe front shell 4, the circuit board 501 and the array element 502 will be removed together, improving the disassembly speed and facilitating user maintenance.

[0029] Working principle: During use, the probe front shell 4 can be connected to the lower end of the probe housing 3. The matching layer and the acoustic lens are installed in the probe front shell 4. After the probe front shell 4 is connected to the lower end of the probe housing 3, the probe front shell 4 can be pressed upward, so that the pin on the lower end of the probe housing 3 is inserted into the probe front shell 4, fixing the probe front shell 4 on the probe housing 3. When pressing the probe front shell 4 upward, the second convex block 605 on the driving frame 601 will drive the circuit board 501 to move upward. When the circuit board 501 moves upward, it will drive the connecting pins 506 on the pin male seat 505 to move upward, so that the connecting pins 506 are inserted into the pin female seat 507. When the connecting pins 506 are inserted into the pin female seat 507, the limit pin 508 will be inserted into the limit slot 504, fixing the pin male seat 505 and the pin female seat 507 together, quickly installing the array element 502 on the circuit board 501. When the array element 502 fails, the probe front shell 4 can be quickly removed. When removing the probe front shell 4, it will drive the driving frame 601 to move downward. When the driving frame 601 moves downward to the bottom dead center, the through hole on the positioning sleeve 604 will be aligned with the through hole on the driving frame 601. At this time, the return spring 606 will push the ejector rod 607 forward. The forward-moving ejector rod 607 will push the limit pin 504 out of the limit slot 508, making the pin male seat 505 loose from the pin female seat 507. When removing the probe front shell 4, the circuit board 501 and the array element 502 can be removed together, facilitating user maintenance of the device.
